Abstract

Bottle choice tests in rats are useful for the study of fat appetite. However, little is known about the feeding behavior of rats toward oxidized oil. In this study, 24-h two-bottle choice tests were performed in male Sprague-Dawley (SD) rats for 5 days. When rats were given a choice between thermally oxidized oil and fresh oil, they ingested more fresh oil. A choice test between vapor-added fresh oil and fresh oil showed that rancid flavor is involved in the avoidance of oxidized oil. Results with deodorized oxidized oil indicated that a nonvolatile product also influenced choice. In conclusion, rats could distinguish oxidized oil from fresh oil and preferred fresh oil.

摘要

大鼠的奶瓶选择试验对于研究脂肪食欲很有用。然而，关于大鼠对氧化油的摄食行为知之甚少。在本研究中，对雄性斯普拉格-道利（SD）大鼠进行了为期5天的24小时双瓶选择试验。当给大鼠提供热氧化油和新鲜油的选择时，它们摄入了更多的新鲜油。在添加了气味的新鲜油和新鲜油之间的选择试验表明，酸败气味参与了对氧化油的回避。脱臭氧化油的试验结果表明，一种非挥发性产物也影响了选择。总之，大鼠能够区分氧化油和新鲜油，并且更喜欢新鲜油。
